[libvirt] [PATCH V4 0/5] support sending sysrq key

xend/libxl support sending sysrq key to guest kernel but not support sending any key sequence as virDomainSendKey is expected to do. To add equivalant sysrq functionality in libvirt for xen/libxl, add a new virDomainSendSysrq API and add related codes to virsh, remote driver, xen/libxl driver. Changes to V3: * fix some memory leak Not change: virDomainSendSysrq parameter still keeps "char key" rather than "enum key", main reason to keep it because: sysrq key is different to different kinds of guests, xen hypervisor doesn't know the correct enum <-> letter mapping towards different guests, it just sends the key blindly to guests.
